Peeling back a level, science is a belief system based on observations. What is a valid observation - if I say I saw it once that is not valid, if I say look in this place or way and you can see it too, well, that is. But what if I say "look in this place and way and you will see this kind of thing once out of a billion trials, and all the other things that are seen are not real"? Science admits that view, and I would not disagree but I am aware that this is a choice - a philosophical view that I have adopted as part of the assumptions that I make to use the belief system that we currently call science. This system is different from the versions of science that were in use 100 years ago, and is changing now with the rejection of intervalism (p=0.05). So bring in 1000 scientists and let them do some philosophy, because to do anything that's what they have to do.
